This document discusses different types of measurement including length, mass, capacity, time, and temperature. It explains the history of measurement and how early humans used body parts to measure. A unit is defined as a fixed standard used to measure something. Common units for length include meters, centimeters, kilometers. Instruments for measuring length are meter sticks and tapes. Mass is measured in kilograms using balances. Capacity in liters is measured using cylinders. Time units are seconds, minutes, hours measured with clocks. Temperature is measured in degrees Celsius or Fahrenheit using thermometers. Conversion between units is also explained.

2. Measurement
 Measurement is the process of finding the size or quality of
something.

3. History of measurement
 In early times, people used different body parts such as the
hand and the palm to measure length.
 Some of the measures used in ancient times were hand
span, cubit, and fathom.

4. Non-standard unit of measurement

5. Unit
 A fixed quality that is used as a standard of measurement is
called a unit.

6. Measurement of length
 Length is the size or measurement of an object from its one
end to another.
 Metre rule and measuring tape are some instruments used
for measuring length.
 The standard unit used to measure length is metre(m).
 Millimetre, centimetre, and metre are used to measure
smaller lengths. Examples are- length of a pencil or a cloth
piece.

7.  Kilometre is used to measure longer lengths or distances.
Examples are- distance between school and home, distance
between Delhi and Mumbai etc.

8.  The units of length can be changed from one to another. For
example,
 10 millimetres (mm) = 1 centimetre (cm)
 100 centimetres (cm) = 1 metre (m)
 1000 metres (m) = 1 kilometre (km)

9.  2.54 centimetres = 1 inch
 12 inch = 1 foot
 3.28084 foot = 1 metre

10. Measurement of mass
 Mass tells us how heavy or light an object is.
 A beam balance or weighing balance is an instrument to
measure mass.
 The standard unit used to measure mass is kilogram (kg).
 Milligram and gram are used to measure smaller mass.

12.  The units of mass can be changed from one to another. For
example,
 1000 milligrams (mg) = 1 gram (g)
 1000 grams (g) = 1 kilogram (kg)

13. Measurement of capacity
 Capacity of a container is the amount of liquid it can hold.
 A measuring cylinder is an instrument used to measure
capacity.
 The standard unit used to measure capacity is litre.
 Millilitre and litre are used to measure smaller capacities
such as water in a bottle. Kilolitre is used to measure larger
capacities like that of a big tank of water.

15.  The units of capacity can be changed from one to another.
For example,
 1000 millilitres (mL) = 1 litre (L)
 1000 litres (L) = 1 kilolitre (kL)

16. Measurement of time
 The period between two events is called time.
 A clock or a watch is an instrument used to measure time.
 Some of the units used to measure time are second (s),
minute (min), and hour (h).

18.  The units of time can be changed from one to another.
 For example,
 60 seconds (s) = 1 minute (min)
 60 minutes (min) = 1 hour (h)

19. Measurement of temperature
 Temperature is the measurement of how hot or cold an
object is.
 It is measured using an instrument called a thermometer.
 Units used to measure temperature are degree Celsius (C)
or degree Fahrenheit (F).
 Doctors use a thermometer to measure of a patient who has
fever.
